What are the development trends of the automotive mold industry's production and sales demand and the transformation and upgrading of forward-looking mold technology?
In the development of automobile mold industry at home and abroad, China's automobile mold industry production and sales demand and transformation and upgrading forward-looking mold technology present the following nine major development trends.
1. The position of mold 3D design is consolidated
The three-dimensional design of automobile molds is an important part of digital mold technology, and it is the basis for the integration of mold design, manufacturing and inspection. Companies such as Toyota and General Motors of the United States have realized the three-dimensional design of molds and achieved good application results. Some methods adopted in the 3D mold design abroad are worthy of our reference. In addition to being conducive to the realization of integrated manufacturing, the three-dimensional design of the mold has another advantage that it is convenient for interference inspection and can perform motion interference analysis, which solves a problem in two-dimensional design.
2. The simulation of stamping forming process (CAE) is more prominent
In recent years, with the rapid development of computer software and hardware, the simulation technology of stamping forming process (CAE) has played an increasingly important role. In developed countries such as the United States, Japan, and Germany, CAE technology has become a necessary part of the mold design and manufacturing process. It is widely used to predict forming defects, optimize the stamping process and mold structure, improve the reliability of mold design, and reduce the number of mold trials for automobile molds. time. Many domestic automobile mold companies have also made significant progress in the application of CAE and achieved good results. The application of CAE technology can greatly save the cost of trial molds and shorten the development cycle of stamping molds, which has become an important means to ensure mold quality. CAE technology is gradually transforming mold design from empirical design to scientific design.
